BACKGROUNDFamilies of children and adolescents with cancer strive to maintain routines and normalcy during the child's treatment trajectory that requires frequent hospital visits. Intravenous chemotherapy at home can reduce time spent on the frequent hospital visits and mitigate disruption in daily life. Studies on home chemotherapy for children and adolescents with cancer are limited, as is knowledge of family and health care professionals' needs, and knowledge required to inform adaptation or replication of interventions in other settings. The aim of this study was to develop and describe an evidence-based home chemotherapy intervention that is feasible and safe for children and adolescents and suitable for future feasibility testing.METHODSThe Medical Research Council's guidance for developing complex interventions in health care and the framework of action developed by O'Cathain et al. was used as theoretical frameworks to structure the development process. A literature search, an ethnographic study, and interviews with clinical nurse specialists from adult cancer departments formed the evidence base. Educational learning theory to support and understand the intervention was identified. Stakeholder perspectives were explored in workshops with health care professionals and parent-adolescent interviews. Reporting was qualified using the GUIDED checklist.RESULTSA stepwise educational program to teach parents how to administer low-dose chemotherapy (Ara-C) to their child at home and a simple and safe administration procedure were developed. Key uncertainties were identified, including barriers and facilitators impacting future testing, evaluation, and implementation. Causal assumptions and reasoning for how the intervention leads to short-term outcomes and long-term impact were clarified in a logic model.CONCLUSIONSThe iterative and flexible framework allowed for integration of existing evidence and new data and was successfully applied to the development process. The detailed report on the development process of the home chemotherapy intervention can enhance adaptation or replication of the intervention to other settings and thereby mitigate family disruption and stress of frequent hospital visits for these treatments. The study has informed the next phase of the research project that aims to test the home chemotherapy intervention in a prospective single-arm feasibility study.TRIAL REGISTRATIONClinicalTrials.gov ID: NCT05372536.

Cytarabine, the 4-amino-1-(β-D-arabinofuranosyl)-2(1H)-pyrimidinone, (ARA-C) is an antimetabolite cytidine analogue used worldwide as key drug in the management of leukaemia. As specified in the manufacturers’ instructions, once the components—sterile water and cytarabine powder—are unpackaged and mixed, the solution begins to degrade after 6 hours at room temperature and 12 hours at 4°C. To evaluate how to avoid wasting the drug in short-term, low-dose treatment regimens, the reconstituted samples, stored at 25°C and 4°C, were analyzed every day of the test week by reversed-phase HPLC and high-field NMR spectroscopy. All the samples remained unchanged for the entire week, which corresponds to the time required to administer the entire commercial drug package during low-dose therapeutic regimens. The drug solution was stored in a glass container at 4°C in an ordinary freezer and drawn with sterile plastic syringes; during this period, no bacterial or fungal contamination was observed. Our findings show that an cytarabine solution prepared and stored in the original vials retains its efficacy and safety and can, therefore, be divided into small doses to be administered over more days, thus avoiding unnecessary expensive and harmful waste of the drug preparation. Moreover, patients who require daily administration of the drug could undergo the infusion at home without need to go to hospital. The stability of the aliquots would help decrease hospitalization costs.

OBJECTIVETo estimate the long-term outcomes and the prognostic factors of homoharringtonine, cytarabine, daunorubicin or idarubicin (HAD/HAI) as induction chemotherapy in de novo acute myeloid leukemia (AML).METHODSThe CR rate, overall survival (OS) rate, relapse free survival (RFS) rate were retrospectively assayed in 143 de novo AML patients who received the HAD/HAI induction chemotherapy. The outcomes were compared among prognostic groups according to world health organization (WHO) classification, genetic prognosis and initial white blood cell (WBC) count. The role of consolidation chemotherapy consisting of middle-dosage Ara-C (MD-Ara-C) on long term survival was evaluated.RESULTSOf 143 patients, 112 (78.3%) achieved CR after the first course of HAD/HAI induction treatment, and early death occurred in only one case. Notably, the CR rate of patients with an initial WBC count ≥100×10(9)/L was not significantly different from those with an initial WBC count<100× 10(9)/L (70.4% vs 80.2%, P=0.266). The CR rate for the patients with favorable, intermediate and unfavorable integrated genetics risk factors was 93.7%, 71.4% and 61.3%, respectively, the difference between groups was statistically significant (P=0.001). Patients with FLT3-ITD mutation obtained similar CR rate (70.6%) to that of patients with FLT3 wild type (79.3%, P=0.528).The estimated 5-year OS rate and 5-year RFS rate for all patients was 40.0% and 37.0%, respectively, with a median follow-up of 24 (range 1-104) months. The median survival time was 30 [95%CI (12, 48)] months. 5-year OS and 5-year RFS of the 96 patients who achieved CR after first course chemotherapy without undergoing allo-HSCT in complete remission was 47.0% and 38.0%, respectively. 5-year OS was significantly higher in MD-Ara-C consolidation group than in no MD-Ara-C consolidation group among CR patients without allo-HSCT (58.0%, 19.0%, respectively, P=0.004). In patients who obtained CR after first course and received MD-Ara-C consolidation without allo-HSCT, the 5-year OS of patients with hyperleukocytosis was not significantly lower than that of patients without hyperleukocytosis (55.5%, 58.8%, respectively,P=0.419). FLT3-ITD mutation patients showed similar 5-year OS to that of wild type FLT3 patients (51.4%, 60.2%, respectively, P=0.482). And furthermore, 5-year OS of favorable, intermediate and unfavorable integrated genetics groups were 59.1%, 62.5%, 51.9%, respectively (P=0.332) in this subgroup.CONCLUSIONHAD/HAI induction chemotherapy with sequential consolidation of MD-Ara-C could obtain satisfactory CR rate and long-term survival rate in de novo AML, especially for patients with hyperleukocytosis or FLT3-ITD mutation. It yet remains to be verified by large sample, prospective studies.
